Title: Pit equipment for moving trucks
Inventor: BARKER WILFRED
IPC: B61J1/10
Filed: 1953-01-20
Abstract: 740,824. Transferring vehicles to and from pit cages. BARKER & SON ENGINEERS, Ltd., W. H. Jan. 12, 1954 [Jan. 20, 1953], No. 1605/53. Classes 78 (4) and 104 (2). Rams feeding trucks between a pair of pit cages and traversers situated at opposite sides of the pit are arranged so that when extended they do not prevent movements of the traversers. The ram heads t of the rams k, m, n of Fig. 4 have carriages mounted on wheels x which run across tracks a<SP>1</SP>, a2, bl, b2, b<SP>3</SP> on the traversers a, b on to tracks f, g, i adjacent a pit top c and a tippler j. After one of the. rams k, m has pushed an empty truck p into one of the pit cages to expel a full truck on to the traverser b, the traverser a is moved to receive a truck from the tippler so bringing the tracks a<SP>1</SP>, a<SP>2</SP> into position to permit retraction of the rams k, m. Similarly, when the ram n has pushed a truck from the track b<SP>1</SP> on traverser b into the tippler j and the traverser is moved to bring the track b<SP>1</SP> adjacent one of the pit cages, one of the tracks b<SP>2</SP>, b<SP>3</SP> is aligned with the track i to permit retraction of the ram n. Alternatively, as shown in plan in Fig. 3, each ram head t may be carried by outwardly facing channel guides u supported by rollers v on fixed supports w so dispensing with the carriage for supporting the ram head. The cylinder q of the ram is mounted between the guides u. The invention may be applied to pit bottom as well as pit top equipment.

Title: Improvements in or relating to knitting machines and to fabrics knitted thereby
IPC: D04B1/02
Filed: 1930-01-20
Abstract: 345,398. Knitted fabrics. McADAMS, H., 4816, N. Mascher Street, Philadelphia, and STARR, J. W., 119, States Avenue, Atlantic City, New Jersey, both in U.S.A. Jan. 20, 1930, No. 1970. [Class 74 (ii).] Pile yarns 60, 80 are laid in at each course to form long projecting uncut loops. The loops of the yarn 60 are drawn to the front of the fabric and this yarn is knitted in, to minimize unravelling, at every fourth, fifth or sixth needle. The loops of the yarn 80 are drawn to the back, and since this yarn is less securely locked in with the base fabric it is knitted in at, preferably every third needle. Weft yarns may also be laid in to reduce stretch. Circular machines for producing the abovedescribed fabric are provided with fixed bearded needles 32 and with rotary sinker wheels F in non- radial slots in which sinkers 119 slide. The non- radial disposition of the sinkers is of advantage in sinking long pile loops. Retraction of these loops upon withdrawal of the sinkers is prevented by a felt pad 130 attached to the push-down cam 110 and held tightly against the needles. A retaining spring also bears against and supports the needles.

Abstract: 371,056. Liquid fuel furnaces. FRASER, R. P., 20, Margravine Gardens, Barons Court, London. Jan. 23, 1931, No. 2298. [Class 51 (i).] An oil burning apparatus comprises an atomizer 1, Figs. 1 and 3, delivering oil sprayed by pressure or air or steam into a forwardly tapering tube 3 or venturi 6 adjustable axially in a casing 5 secured to the front plate 2 of the boiler or furnace, hot air and combustion products being drawn from the combustion space into the tube or venturi through the passage between an inner tube 4 or the venturi 6 and the casing 5. The ignition point is thereby maintained constant at the small end of the tapered tube or at the throat of the venturi. The venturi or casing may be divided by one or more partitions or vanes. In the construction shown in Figs. 7 and 8, air is drawn through the corner passages 8 formed between the circular end of the venturi 6 and the rectangular casing 5 and the flame is divided by divergent vanes 7, which also act as vaporizing surfaces. A pilot gas jet 9 or an electric sparking device is provided between the vanes for ignition purposes. A shield 12 at the front of the casing prevents the air flow over the external surface of the casing from affecting the flame. In another construction the casing and a forwardly tapering tube provided with lateral air admission apertures are formed as an integral unit.

Abstract: 1,042,672. Velocity-modulated tubes. STANDARD TELEPHONES & CABLES Ltd. Jan. 17, 1964 [Jan. 18, 1963], No. 2314/63. Heading H1D. The electron beam in a reflex klystron is reflected by means of a magnetic field, which field is preferably substantially radial with respect to the beam axis. The surface of a cathode 1, Fig. 2, is shaped to project an electron beam through an annular aperture 5 into a toroidal cavity resonator 7, the top wall of which is formed by a central magnet polepiece 8 and an annular surrounding polepiece 9 separated by a copper insert 10, and which is coupled to a waveguide 16 by a coaxial feeder 12. The radial magnetic field reflects the electron beam by transforming its upward axial motion first into circular motion around the axis, and subsequently into downward axial motion. In a modification (Fig. 3, not shown) the electron beam passes through both walls of the resonator before being reflected. In a further modification, Fig. 6, the beam is reflected by the radial component of an axially increasing magnetic field provided by the polepieces 41, 50, 51, the middle one serving as the electron gun anode, and the upper one including a waveguide window 53 and dielectric rod 54 for coupling to an output waveguide 16.

Abstract: 474,599. Reamers, taps, and milling- cutters. STAPLES, E. M. Jan. 29, 1936, No. 2689. [Class 83 (iii)] A reamer, tap, milling-cutter, or like circular cutting tool comprises a cylindrical body portion with longitudinal cutting elements on its outer surface and means for expanding said body portion arranged within a cavity thereof, said means being adapted to contact with the inside of the body portion along narrow areas or lines substantially parallel with the forward edges of the cutting elements and so disposed as to outwardly expand the body adjacent to the cutting elements to impart simultaneously clearance to the cutting elements. In a reamer, Figs. 3 and 4, a tapered polygonal plug 29, the edges of which contact the cylindrical interior 23 of the hollow portion of the body, is driven into the body to adjust the cutting blades 20. The hollow portion carrying the cutting blades tends to conform to the tapered plug and so the cutting blades are tilted in the direction to impart clearance to them. The tapered plug may be held and adjusted by various screw means. In a modification the interior of the body may be polygonal and the tapered plug may be plain, and in a further modification, Fig. 7, projections 36 on the interior of the body may engage cam surfaces 35 on a rotatably adjustable plug 29, graduations being provided to facilitate adjustment. Any of the expanding means described as applied to reamers may be used for adjustable taps. A milling-cutter embodiment of the invention, Fig. 14, comprises an interiorly fluted body portion 21, the points of least diameter of the interior being directly under the cutting edges of the blades 20 and adapted to be engaged by a conical plug 30 screwed to a hub 29 integral with an end flange 38. The latter is adjusted relatively to the body portion to expand the - cutter and locked by a key-piece (not shown) which is adapted to break on overload. A screwed disc 40 makes up the other side face of the cutter and locks the conical piece 30 on the hub 29.
